Last night May 20, we took some spectra of some stars in our chosen favorite constellations. Using mercury emission lines to calibrate our spectra, we produced the following spectra for the indicated stars. Note the characteristic Balmer series of hydrogen absorption in Regulus.

Nuclear group at MoNA collaboration meeting
These are the MoNA collaborators at Westmont College. This morning Eric Lunderberg and Paul DeYoung, showed them how to sort our 13Li->11Li+2n data files so they can develop algorithms for finding events containing exactly two neutrons. This was done via videoconferencing and desktop sharing since they are located in California.
May Term Night Sky Class
Today the Night Sky Class took a solar spectrum using the SBIG SGS spectroscope. Mercury emission lines from a florescence lamp provided the calibration. Here is our calibrated image. We had an imaging session on May 14th and captured a favorite galaxy, the Whirlpool Galaxy M51 in Canes Venatici. M51 is estimated to be about …
Inside the accelerator scattering chamber
This is the inside of the vacuum chamber. The dislodged target is hard to see but is on the ring (with angle marks) sort of behind things in the lower right. This is Graham Peaslee making sure that the set of targets that have been dislodged from the target mechanism are not going to jam …

Snapshots of Today’s Research
Summer research in the Physics Department has gotten off to a great start. Students in Steve Remillard’s group and Paul DeYoung/Graham Peaslee’s group started this week. Other students will start next week and in the following weeks. Jenny Hampton walked around the department this afternoon and took a few pictures of what students were doing. …
